7th Unit 3 Review

Front

Which layer represents the crust?

Back

The crust is the outermost layer of the Earth, consisting of solid rock and soil.

Front

What forms at a divergent boundary between two oceanic plates?

Back

A mid-ocean ridge forms at a divergent boundary, where two oceanic plates move apart.

Front

What causes tectonic plates to move along the Earth's surface?

Back

Tectonic plates move due to convection currents in the mantle, which is caused by the heat from the Earth's core.

Front

What is the main method of heat transfer from the core to the crust of Earth?

Back

Convection is the main method of heat transfer from the core to the crust, involving the movement of molten rock.

Front

A trench forms at a _________ boundary.

Back

A trench forms at a convergent boundary, where one plate is forced under another.

Front

What is the Earth's outer layer called?

Back

The Earth's outer layer is called the lithosphere, which includes the crust and the upper mantle.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often found on land.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle provides the heat and convection currents that drive the movement of tectonic plates.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.
